Hi , i'm new with flex an dthis list, not with actionscript and flash.

my problem is, i have a mx:List and it's data comes out of a xml which
i get from the server.

it's a list of provinces, and they have a name and an id.

I want to send the id back to the server when someone selects a
province.

i fill the list with dataProvider. But when i show the name of
province, the listId.value is also the name of the province, but i
want the value to be the id.

Is there a way to show Province name in the list, and let the province
id be the value?

I have a custom event that holds an array element. When I dispatch an 
event from a pop up window - by dispatching it from the 
mx.core.Application.application object - with data assigned to the 
array the event fires correctly, however, the data array element is no 
longer assigned any data. Also the event object still has the 
data:Array property, so the program recognizes it as my custom event, 
it just does not have any data anymore. Why is this? 

 

RE: [flexcoders] Re: Can't select an item renderer in a list

[Alex Harui]

The UID's in the data, not the renderer matter.  Renderers definitely
get recycled so you can't store anything about selection in the renderer
and have to use isItemSelected to update it during updateDisplayList.

 

If you want to post a mini-example, we can take a look.

No I do not have the same problem if I use the default renderer.
I checked the UIDs in the following manner :

- Manually changing the UID of each renderer to make sure they are
unique

- Using debug mode and monitoring the UID : they are different. 

In both cases tho the behavior of this bug is exactly the same :

Behavior of the list during a drag and drop is to create 2 new renderer:

1 that represent the item being dragged which will never make it to
the list. (So that new item doesn't cause the bug)
1 that will take the place of the item that you dragged but will
contain the info of the item next to it.

That last item for whatever reason will be considerer by the list's
selection model as the last item in the list.

So while you can still see the other items in the list you can no
longer rollover / select them.

If I repopulate the list by changing the list's dataProvider then for
some reason the list will use the renderer's already there but in
reverse order. That means that the first item is selectable but none
of the following items will be.(Unless the new list is longer than the
old one which means that all the new items which will require new
renderers will then be selectable)

Hope this help clarify !

RE: [flexcoders] Size list or DG column to widest content

[Alex Harui]

Well, you have to measure every item in the DP which can take a while.
Then, if horizontalScrollPolicy="on" it should honor the size, but if
the policy="off" (default), it gets a bit trickier because in that mode,
the DG will resize columns inorder to fit them all on screen.  You can
try setting resizable="false" and then flipping it back to true later if
you want to let folks resize it later.

[flexcoders] Re-Scaling Charts when a series is made visible / invisible

[cuddlygunchi]

Hello,

I give the user an option to make a series visible / invisible in a 
chart. However, the Y axis is always scaled according to the largest 
value a series can take, no matter if its visible or not.

How can I make the Y axis scale according to only the visible series in 
my chart? 

I could perhaps get this effect if I remove the series item instead of 
just setting its visible to false. But when I dynamically add / remove 
series to the array, it does not recreate the chart and all the series 
just stay there.

Many Thanks,

[flexcoders] Visual modelling program - which direction should I take? Z-order info?

[Josh McDonald]

Hi Guys,

I'm about to start working on a program to display some XML data as a
visual model. It requires various boxes-within-boxes and connecting
lines. Before I go and do it all wrong, I have a few concerns and
questions for anybody who's done this sort of thing before.

Should I be creating custom nested components, or just drawing on a big canvas?
If I'm using components, how will I layer the connecting lines above
the other components?
Is there an easily accessible universal x/y/z position system to
access those details, or will I be going up various trees adding
top/left offsets until I get to the Application object?
Are there any examples or articles on doing this sort of thing I should look at?

Any suggestions or pointers to similar projects would definitely be appreciated!

Cheers,
-Josh

You have easy control over the way each node is displayed, via

It also seems that events do not bubble over to pop-up windows.

VS is a far more polished IDE than FB2 - FB3 will close the gap a bit
but not all the way. But some interesting things are developing in
terms of delivering sample code and the framework documentation might
actually be easier to digest than MS's.

I'm on the front side of the same learning curve but my impression is
that the UI is way easier to code for than .net provided you code to
best practices and patterns. It looks to me like opportunity to map
the same objects on both sides of the data tier
(http://flex.sys-con.com/read/418939.htm#) could give us the best of
both worlds - the advantage of sproc-based data-managment filtered by
.net assemblies feeding the Flex's rich UI.

If you want to focus that narrowly on the CRUD aspect to Flex code you

//on of the subclass's
public class B extends A{

//subclass method
override public function getBla(bla1, bla2, bla3, bla4 ){
bla1 and bla2 are inherited automatically
bla3 and bla4 are defined
}
}

import flash.display.Sprite;
import packageName.*;

//the main class
public class mainClassName extends Sprite{

private var theBla:B;
public function mainClassName(){
theBla.getBla();
}
}
}

Anyhow it didn't work. It seems that overriding does just that and
only that, "overide". The compiler will not let me add Bla3 and Bla4
without throwing an error. Also I can't remove the keyword override
because the compiler thinks I am trying to override the Method when all
I am really trying to do is update the method.

Another problem I am trying to work out is data types. Not only
does flash expect you to data type your parameters, but it also expects
you to data type the methods. I am sure that I have some sort of
misunderstanding about this, but here is my flawed interpretation
anyways.

public function getBla(bla1:String, bla2:String):String{
bla1 = 'bla bla bla';
bla2 = 'bla bla bla';
}
But what if I want to add a string and a numeric type in the same
method? Then what what datatype do I declare my method to be?

public function getBla(bla1:String, bla2:int):???{
bla1 = 'bla bla bla';
bla2 = 123;
}
And if I am actually successful overiding or updating or whatever a
method in a subclass, then how do I data type the subclass or base class
for that matter?

//base class
public function getBla(bla1:String, bla2:String):?String?{
bla1 = 'bla bla bla';
bla2 = 123;
}

//subclass
public function getBla(bla1:String, bla2:String, bla3:int,
bla4:int):???{
bla3 = 456;
bla4 = 123;
}

Also, if you notice that some of my terminology is off, then please feel
free to correct me. I am still a learning the basics.

Thanks,

RE: [flexcoders] Can't select an item renderer in a list

[Alex Harui]

Double check the UIDs.  Try using the default renderer and see if you
still have the problem.

Subject: [flexcoders] Can't select an item renderer in a list

 

Greetings everybody,
I have a peculiar problem. I have a list that is rendered by a custom
item renderer. The list allows multiple selection and also drag and
drop operation (in order to shuffle the item around)

However when I move an item further down the list (drag & drop) then I
can't select the items that are below the item immediately following
the item I moved.

Also if I change the content of my data provider, I will experience
the same thing (can't select the items except the first one)

I found out something very interesting :
It seems that my list doesn't allow me to select items which the
renderer is older (has been instanciated before) the previous renderer.

Allow me to demonstrate :
If I have the following renderers :

Renderer1
Renderer2
Renderer5
Renderer3
Renderer4

And assuming the number after 'renderer' indicates the order into
which the renderer have been instanciated in my list then in the above
situation I will not be able to select or rollover Renderer3 and
Renderer4...

This I believe is the problem that happens when I do a drag & drop
operation and or when I reload my list by changing the DataProvider...

N.B. : I use only 1 class for my renderer so all renderers are of the
same type. I have also checked their UID and they seem to be distinct
as far as I can tell...

Hope you guys can help cuz this is really bothering me...

Thanx for your attention !

[flexcoders] "Enter Thru" States

[dmeasbp]

Hello All!

I simply have a number of states, which alter a viewstack, which
contain Panel components.  I want to be able to 'RETURN' or 'ENTER'
thru the states.  Should I add an event listener to the application? 
Any help would be appreciated.

[flexcoders] classes

[Donovan]

I am not a Flex user, I don't know how to do that yet. But here is my
problem anyways.

I have been working on my final project for school.  I set up all my
classes.  I was having difficulty with getting them to work.  My base
class contains all the data that is necessary to set up the all the
class that follow. For example.

package packageName{

 //the base class
 public class A{

 //the base class method
 public function getBla(bla1, bla2){
 bla1 defined...
 bla2 defined...
 }
}

package packageName{

 //on of the subclass's
 public class B extends A{

 //subclass method
 override public function getBla(bla1, bla2, bla3, bla4 ){
 bla1 and bla2 are inherited automatically
 bla3 and bla4 are defined
 }
}

package{

 import flash.display.Sprite;
 import packageName.*;

 //the main class
 public class mainClassName extends Sprite{

 private var theBla:B;
 public function mainClassName(){
 theBla.getBla();
 }
 }
}

[flexcoders] extending flex builder component panel

[northwood Lee]

Hi,
This is a question about how we can extend flex builder itself

 the *component *panel. see attachment(components.jpg).

since flex builder is based on eclipse, I am wondering if we can extend the
Flex Buidler 3 （or build an eclispe plugin）so that the componet panel could
show the customized componets in different groups.

for example, we could have a group button , and uder this group, it shows
the different customized button components see, (components_mockup.jpg).

Many many thanks

[flexcoders] There has been an I/O Error: Error #2038

[FlexCoders]

FLEX 2 

I have a Flex upload project that gets this error at the end. It actually
uploads the file but at the end it tosses out this error. I am not sure why
this is happening. I will upload a file and it will complete. Then it will
toss out the error:

There has been an I/O Error: Error #2038



I click Okay and then the error:

There has been an http error: status code 500



I am running this application on Windows server 2003 enterprise.
IIS 6 

Anyone know why this is happening?

Re: [flexcoders] Drag and drop question

[Daniel Freiman]

Use a bitmap of the target instead of the original target.

///
var target:UIComponent = event.currentTarget as UIComponent;
var dragProxy:Bitmap;
var myBitmapData:BitmapData = new BitmapData(target.width, target.height);
myBitmapData.draw(target); // draw target onto bitmap
dragProxy = new Bitmap(myBitmapData);

[flexcoders] LCDS, AIR and Client Side Cacheing

[christophers1228]

Hello,

Is it possible to enable client side caching with AIR and LCDS when
you have managed destinations?

For example, if I have 4 related tables each having their own destination.

SalesPerson has many WorkOrders.
WorkOrder has one SalesPerson.
WorkOrder has many Proposals.
Proposal has one WorkOrder.
Proposal has many LineItems.
LineItem has one Proposal.

If I have the following mxml code.



workOrderDS.fill(model.workOrders,
'WorkOrderVO.getWorkOrdersForSalesPerson', {user: model.user.id});

Thanks for any pointers.

[flexcoders] Drag and drop question

[msabljic]

Hi,

I  am  trying to drag an UIComponent instance over an Image object and
drag  and drop work fine but i am having problem with dragProxy image.
I  would  like to use my original drag source UIComponent as dragProxy
image but if i do the following:


public function dragItSubs(event:MouseEvent):void{

// Get the drag initiator component from the event object.
var dragInitiator:UIComponent = event.currentTarget as UIComponent;

/  
var dragProxy:UIComponent = new UIComponent;
dragProxy = event.currentTarget as UIComponent;
/

// Call the DragManager doDrag() method to start the drag. 
DragManager.doDrag(dragInitiator,  event, dragProxy);

}


then  the  original  UIComponent  (which  is a drag source) is used as
dragProxy  while  dragging  it but that same component dissapears from
its  original  position  as  soon as dragging starts. How can i accomplish
that  drag  source  UIComponent's "image" is used as dragProxy but the
same source drag UIComponent is intact while dragging?

thanks in advance

Re: [flexcoders] Re: Where to do heavy lifting in a Flex app? (no threading?)

[Richard Rodseth]

I don't know how the Flash Player is implemented, but I would expect
C/C++. See also:

http://developer.mozilla.org/en/docs/Tamarin

Remember the player has a long history and download size has always
been a priority. It wouldn't make sense to build one VM on top of
another (relatively heavy) one. I've no idea how the poster got this
idea.

This message thread has revolved around the need for threading in Flash Player, 
but where it 
is really a must is in AIR.
With AIR you may well not even have  server to offload tasks to. It may as well 
be a 
standalone app around a sqlite db. Threading will be in much more demand there.

I believe this will be a recurring topic in the near future.
